Detailed description of the invention
Below, with reference to accompanying drawing, the example for embodiment of the present invention is described.
Fig. 1 is the sectional view of an example of the formation method of film for illustration of present embodiment.
(the 1st operation)
First, prepared substrate 10.Substrate 10 can use usually baseplate material used.Such as glass, PET (PET), PEN (PEN), polyether sulfone (PES), PEI, polyether-ether-ketone, polyphenylene sulfide, polyarylate, polyimides, Merlon (PC), cellulose triacetate (TAC), cellulose-acetate propionate (CAP) etc. can be used.
Further, as required substrate 10 is cleaned.For cleaning method, the conventional methods such as Ultrasonic Cleaning can be used.Afterwards, UV (ultraviolet: ultraviolet) is irradiated for substrate 10.For the irradiation of UV, use conventional UV irradiation unit, expect the ultraviolet irradiating below 200nm (such as 10nm ~ 200nm) wavelength.By irradiating UV, remove the impurity on substrate 10 surface, thus can hydrophiling.
(the 2nd operation)
Then, for substrate 10, spray by the mist formed containing fine-grained dispersion liquid, carry out the film forming of metal oxide film 2.
Fig. 2 is the figure of an example of the film formation device illustrated in present embodiment.Film formation device has generation containing the 1st groove of fine-grained mist, as making the 2nd groove of the mist collector of mist homogenising, substrate 10 being carried out to the 3rd groove of the spraying of mist.
Contain material solution 5 in 1st groove, this material solution 5 is the dispersion liquid of microparticulate in dispersant.Particulate can use indium, zinc, tin or titanium etc. to have the metal particle of electric conductivity, contain the metal oxide microparticle of wherein at least one.They can be used alone, and also can be combined two or more and use.The nanoparticle of particulate to be particle diameter be 1 ~ 100nm.It should be noted that, as particle diameter, the major axis of the particulate such as obtained according to SEM image and the mean value of minor axis can be used.It should be noted that, in the present embodiment, be described as the mode of particulate to use metal oxide microparticle.
As long as dispersant can disperse particles, alcohol and their mixtures such as water, isopropyl alcohol (IPA), ethanol can be used.It should be noted that, in the 1st groove, flow into air 22, for the formation of the stream of mist.
In addition, ultrasonic oscillator 21 is contained in the 1st groove.Utilize this ultrasonic oscillator 21, the dispersion liquid containing metal oxide microparticle is atomized.The particle diameter of mist expects to be less than 10 μm (such as 1 ~ 10 μm).The mist generated in the 1st groove, via the pipe being arranged on the 1st groove, transports to the 2nd groove.In the 2nd groove, excessive mist accumulates in the bottom of groove, and the mist of uniform particle sizes, via the pipe being arranged on the 2nd groove, transports to the 3rd groove.For from the 2nd groove to the 3rd groove, expect the mist of the particle diameter being configured to conveyance less than 5 μm (such as 1 ~ 5 μm).
In the 3rd groove, placement substrate 10, is sprayed to substrate from the mist of the 2nd groove conveyance.In the 3rd groove, with the stipulated time substrate 10 carried out to the spraying of mist.Further, by being attached to the dispersant vaporization of the mist of substrate 10, thus metal oxide film is formed on substrate 10 surface.It should be noted that, after spraying after certain hour, before mist is vaporized, on the substrate 10, the dispersion liquid of droplet treatment flows down thus, cannot form uniform metal oxide film on the substrate 10 in new mist attachment.Stop the time of the spraying of mist for the moment that liquefaction occurs the mist containing metal oxide microparticle and flow down from substrate 10, also can be the moment of the metal oxide film forming desired thickness on the substrate 10 for substrate 10.
In the 3rd groove, during superheated substrate 10, substrate 10 is likely out of shape owing to softening.Therefore, in the 3rd groove, carry out the spraying of mist under being desirably in the temperature lower than the softening point of substrate, form metal oxide film.In addition, during the spraying of mist, when being heated to more than set point of temperature by substrate 10, be attached to the metal oxide microparticle aggegation of substrate 10, the metal oxide film of formation has high resistance.Therefore, carry out the spraying of mist under expecting to be configured to the temperature of below 40 DEG C (such as 10 DEG C ~ 40 DEG C) further, form metal oxide film.
It should be noted that, herein, softening point refers to: during heated substrates, and substrate softens, and starts the temperature producing distortion.It can utilize such as obtains according to the test method of JISK7207 (A method).
Detailed content will, in description, when formation metal oxide film selective for substrate 10, by scolding moisture film for the selective formation of substrate 10 in advance, make mist be attached to hydrophilic portion.Now, if substrate 10 horizontal arrangement, be then attached to and scold the dispersion liquid in water portion not scolded water, cannot selective formation metal oxide film.Therefore, in the 3rd groove, expect the spraying substrate 10 be inclined relative to horizontal being carried out to mist.
Similarly, in the 3rd groove, expect the spraying substrate 10 relative to the face tilt orthogonal with the spray direction of mist being carried out to mist.This is in order to the impulse force removal of the spraying with mist is attached to the excessive metal oxide microparticle of scolding water portion.
It should be noted that, film formation device can omit the mist collector of the 2nd groove.In it is possible to the film forming of with easier device, substrate being carried out to metal oxide film.
In addition, for the production method of mist, make except using above-mentioned ultrasonic oscillator 21 except it produces, can also use: to the tubule of spraying droplets directly being applied voltage to produce the electrostatic of mist; The gas and the liquid that increase flow velocity by making applying pressure collide, thus make the adding pressure type that the mist of generation disperses; The dish of High Rotation Speed instils drop, makes the rotating disc type that the mist of generation disperses under centrifugal action; The restricting orifice with micro-scale pores circulates drop, now cutting off drop by utilizing piezoelectric element etc. to apply vibration, producing the throttle orifice oscillatory type etc. of micro-dimension drop thus.For the production method of mist, according to cost, performance etc., suitably select these methods.Two or more methods can certainly be combined to produce mist.
(the 3rd operation)
Return Fig. 1 to be described.Afterwards, for the substrate 10 being formed with metal oxide film 2, carry out heating to make it dry.In the same manner as above-mentioned example, expect that heating-up temperature is now at the temperature of the softening point lower than substrate 10.Heating can be carried out under the low vacuum of about 30Pa, also can carry out under Ar gas atmosphere.For hot situation, according to the situation etc. of film forming, suitably distinguish use.It should be noted that, in this operation, drying is carried out in non-essential utilization heating.Such as at normal temperatures, substrate 10 can be set with the stipulated time, carry out drying thus.
It should be noted that, above-mentioned 1st operation is not necessary operation.It is the operation of carrying out as pre-treatment, in order to make mist adhere on the substrate 10 in the 2nd operation, as long as therefore mist attachment on the substrate 10, does not limit method.
By above process, forming metal oxide film on the substrate 10, as required, by again carrying out the process from the 1st operation to the 3rd operation, the 2nd layer of metal oxide film can be obtained.In this situation, the base-plate cleaning of the 1st operation can be omitted.It should be noted that, by making in the mist of the 1st layer contained metal oxide microparticle be identical material with the metal oxide microparticle of the 2nd layer, the metal oxide film of abundant thickness can be obtained.Or by making the metal oxide film of the 1st layer be different materials from the metal oxide film of the 2nd layer, can according to purposes, object and distinguish use conducting film.
Above, in the present embodiment, in the formation process of film, substrate is not heated when carrying out film forming.Therefore, it is possible to obtain the low metal oxide film of resistance value.In addition, even if for heat labile substrate, also effectively film forming can be carried out.
